In this study, factor analysis was used to examine whether men and women experience loneliness differently and how marital status affects the experience of loneliness (especially if the marriage is terminated). The experiences of chronic and situational or event-related loneliness are also compared. Finally, the study is also an investigation of the social stigma that causes people to refuse to admit their loneliness. As a result of this stigma, when questioned for research purposes, individuals usually report a recall of past loneliness rather than a current or ongoing experience. In the present study, the difference between loneliness recalled and loneliness experienced at the time of questioning is investigated.  相似文献

This paper presents five studies with 2,420 total participants on the development and validation of the Exercise Dependence Scale (EDS), which is conceptualized based on the Diagnostic and Statistical Manual-IV (APA, 1994) criteria for substance dependence, and differentiates among at-risk, nondependent-symptomatic, and nondependent-asymptomatic exercisers. Results of the studies revealed evidence for the a priori hypothesized components, acceptable test-retest and internal consistency reliability, and content and concurrent validity of the EDS. Individuals at-risk for exercise dependence reported more strenuous exercise, perfectionism, and self-efficacy compared to the nondependent groups. The findings provide initial support for the EDS and indicate the need for a multifaceted approach to its conceptualization and measurement.  相似文献

Delayed rewards are less valuable than immediate rewards. This well‐established finding has focused almost entirely on individual outcomes. However, are delayed rewards similarly discounted if they are shared by a group? The current article reports on three experiments exploring the effect of group context on delay discounting. Results indicate that discount rates of individual and group rewards were highly correlated, but that respondents were more willing to wait (decreased discounting) for shared outcomes than for individual outcomes. An explanatory model is proposed suggesting that decreased discount rates in group contexts may be due to the way the effects of both delay and social discounting are combined. That is, in a group context, a person values both a future reward (discounted by delay) and a present reward to another person (discounted by the social distance between them). The results are explained by a combined discount function containing a delay factor and a factor representing the social distance between the decision maker and group members. Practical implications of the fact that shared consequences can increase individual self‐control are also discussed. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Numerous studies have provided clues about the ontogeny of lateralization of auditory processing in humans, but most have employed specific subtypes of stimuli and/or have assessed responses in discrete temporal windows. The present study used near-infrared spectroscopy (NIRS) to establish changes in hemodynamic activity in the neocortex of preverbal infants (aged 4–11 months) while they were exposed to two distinct types of complex auditory stimuli (full sentences and musical phrases). Measurements were taken from bilateral temporal regions, including both anterior and posterior superior temporal gyri. When the infant sample was treated as a homogenous group, no significant effects emerged for stimulus type. However, when infants’ hemodynamic responses were categorized according to their overall changes in volume, two very clear neurophysiological patterns emerged. A high-responder group showed a pattern of early and increasing activation, primarily in the left hemisphere, similar to that observed in comparable studies with adults. In contrast, a low-responder group showed a pattern of gradual decreases in activation over time. Although age did track with responder type, no significant differences between these groups emerged for stimulus type, suggesting that the high- versus low-responder characterization generalizes across classes of auditory stimuli. These results highlight a new way to conceptualize the variable cortical blood flow patterns that are frequently observed across infants and stimuli, with hemodynamic response volumes potentially serving as an early indicator of developmental changes in auditory-processing sensitivity.  相似文献

Often, when children testify in court they do so as victims of a repeated offence and must report details of an instance of the offence. One factor that may influence children's ability to succeed in this task concerns the temporal distance between presentations of the repeated event. Indeed, there is a substantial amount of literature on the “spacing effect” that suggests this may be the case. In the current research, we examined the effect of temporal spacing on memory reports for complex autobiographical events. Children participated in one or four play sessions presented at different intervals. Later, children were suggestively questioned, and then participated in a memory test. Superior recall of distributed events (a spacing effect) was found when the delay to test was 1?day (Experiment 1) but there was little evidence for a spacing effect when the delay was 1 week (Experiment 2). Implications for understanding children's recall of repeated autobiographical events are discussed.  相似文献

Although Black1For the sake of simplicity, the generic terms Black and White are used to denote differences between the two groups of women. and White women’s relationships have received considerable attention, the important questions of how and if these relationships change with age and social class have received less attention. This article using the metaphor of intersectionality, and grounding women’s relationships in historically and contextually relevant frameworks, provides an understanding of the social and cultural tensions that continue to influence the standpoints of aging middle class Black and White women. The authors pose many probing questions about whether or not aging middle class Black and White women are capable of developing genuine friendships rather than superficial acquaintanceships. The article concludes with implications for Black and White feminist therapists, which highlight the necessity for personal reflections about issues of power and oppression and how they permeate interactions, depth of historical knowledge, and the promotion of positive aging techniques. Each of these and others help to forge a greater understanding of relationship building between these two groups of heterogeneouswomen.  相似文献

People spend a considerable amount of their time mentally simulating experiences other than the one in which they are presently engaged, as a means of distraction, coping, or preparation for the future. In this integrative review, we examine four (non‐exhaustive) cases in which mentally simulating an experience serves a different function, as a substitute for the corresponding experience. In each case, mentally simulating an experience evokes similar cognitive, physiological, and/or behavioral consequences as having the corresponding experience in reality: (i) imagined experiences are attributed evidentiary value like physical evidence, (ii) mental practice instantiates the same performance benefits as physical practice, (iii) imagined consumption of a food reduces its actual consumption, and (iv) imagined goal achievement reduces motivation for actual goal achievement. We organize these cases under a common superordinate category and discuss their different methodological approaches and explanatory accounts. Our integration yields theoretical and practical insights into when and why mentally simulating an experience serves as its substitute.  相似文献
